Maybe? Maybe not? It's gotten its implementation details pretty intertwined with rt/task.rs and rt/kill.rs by now.

But many of the test cases in it should actually be in task/mod.rs (and the linked failure tests in task/mod.rs should be in it...).

Also also I think the pub mod spawn declaration in task/mod.rs should be private?

rt::taskgroup. The spawn module is probably public because of some resolve bug. Should be private.

auto merge of #10603 : alexcrichton/rust/no-linked-failure, r=brson

The reasons for doing this are:

* The model on which linked failure is based is inherently complex
* The implementation is also very complex, and there are few remaining who
  fully understand the implementation
* There are existing race conditions in the core context switching function of
  the scheduler, and possibly others.
* It's unclear whether this model of linked failure maps well to a 1:1 threading
  model

Linked failure is often a desired aspect of tasks, but we would like to take a
much more conservative approach in re-implementing linked failure if at all.
